[1] Schönberg attended the Imperial and Royal Unified Academy of Fine Arts in Vienna from 1858 to 1860, where his father had also studied.

[1] Schönberg was of military age and served as a soldier in the Austrian army and fought in the Battle of Custoza (1866) as part of the Third Italian War of Independence.

[4] In 1901, when Schönberg was in China, the census shows Pauline was staying with a cousin in Ernst Carl Fuchs at Penge in Kent.

By the 1911 census, the couple, now in their 60s were boarding with the Bruck brothers, Walter, a fine art publisher, and William, a process engraver, in Weylands, 21, Southend Road, Beckham.

Wurzbach noted that Schönberg's sketches were well drawn, gave a faithful rendering of the scenes, and when many people were represented, the groups were cleverly distributed and the timing of the drawing chosen with a lucid eye.

It was a long drawn out process as he first had to produce watercolour sketches and mid-sized oil paintings to get approval for the large-scale oil-paintings.

[8] Schönberg provided illustrations for many publications, starting in his native Austria and then moving further afield to Germany, France, and England.

Schönberg was a correspondent as well as an artist and sent reports and conducted interviews, in addition to sending sketches of the action or of the aftermath of war.

Schönberg did twelve full-page illustrations as line-and-wash drawings reproduced by black line and sepia tint plates.

[11]: 130  Newbolt notes that Schönberg's work was limited by the quality of available processes and sometimes by the printer's choice of cheap paper.
